本文以“硝酸钾晶体的制备”为例,结合自己的教学实践,探讨如何进行《实验化学》课题实验的复习。一、梳理实验流程,回归教材核心问题苏教版《实验化学》教材在教材结构、实验课题编排和内容选择等方面都作了精心设计。有些课题实验以前从没做过也从没考过,没有直接的经验可以借鉴。在高考复习中如何落实教材内容,挖掘课题实验资源,显得相当重要。
In this paper, “preparation of potassium nitrate crystals” as an example, combined with their own teaching practice, to explore how to carry out “experimental chemistry” experiment review. First, sort out the experimental process and return to the core issues of the textbook Sujiao version of “Experimental Chemistry” textbook has been carefully designed in terms of textbook structure, experimental topics and content selection. Some subjects have never been tested before the experiment never had no direct experience can learn from. In the college entrance examination review how to implement the textbook content, mining subject experimental resources, it is quite important.
